Police use water cannon to disperse rioting Loyalists on the Newtownards Road in Belfast, Monday, Jan. 7, 2013, a month after the City Council decided to fly the union flag on designated days only. Protesters have been out in force — with sometimes violent results — since a Dec. 3 decision by Belfast City Council to stop flying the British flag year-round. Such issues of symbolism frequently inflame sectarian passions in Northern Ireland, where Protestants mainly want to stay in the United Kingdom and Catholics want to unite with the Republic of Ireland.
